Blue Origin completes BE-4 hot fire test

Jeff Bezos of Blue Origin sent a tweet out today with the news that they had completed the first hot fire test of their BE-4 engine which will be used to power their New Glenn rocket and could also be selected by United Launch Alliance (ULA) to power their Vulcan rocket.

While results of the test are not currently available this is an important step for Blue Origin as it moves them closer to both New Glenn and also selection by ULA. We look forward to seeing how the tests progress.
